REVERSIBLE SASH.

Specification of Letters Patent.

Application filed May as, 1917. Serial No. 170,405.

To all whom it may concern:

Be it known that I, Momma BRAND, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented cer tain new and useful Improvements in Reversible Sashes, of which the following is a specification.

This invention relates to certain new and useful improvements in reVersible window sash and it has for its objects-among others to provide a simple and improved form of.

straight, the opening is clear from top to bottom.

It has for a further object to provide means for stiffening and strengthening the sash and frame and further means for forming a water-tight and weather-proof joint at the sides of the sashes.

In the present construction I dispense with the raising and lowering of the sash and thus do away with the cost of weights, sash cords, and pulleys and the expense of framing for their insertion, as well as gaining spaceabout seven inchesin width space of the opening in the wall for the frame, which is a big desideratum in gaining space for glass in the sash.

n the present structure there is no cross bar at the junction of the sashes and the structure, as a whole, is greatly simplified and cheapened.

Other objects and advantages of the in-' vention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claim.

The invention is clearlyillustrated in the accompanying drawings, which, with the numerals of reference marked thereon, forma part of this specification, and in which Figure 1 is an elevation of a window showing my present improvement.

Fig. 2 is a substantially central vertical section through the same.

Fig. 3 is a perspective detail of a portion of a sash with parts broken away.

Fig. 4 is a similar view of the other sash with parts broken away.-

Fig. 5 is a vertical section on the line 5-5 of Fig. 1, looking in the direction of the arrows.

Fig. 6 is an enlarged detail on the line 66 of Fig. 1, looking in the direction of the arrows.

Fig. 7 is a detail in elevation of the meeting edges of the two sashes.

Fig. 8 is a section on the line 8-8 of Fig. 7 looking in the direction of the arrows.

Fig. 9 is an enlarged detail in elevation with portions broken away showing the lower right-hand'corner of the window frame.

Like numerals of reference indicate like parts throughout the several views.

Referring to the drawings,

1% designates a window frame and 2 a s1 s 3 is the'upper sash and 4 the lower sash. The upper sash is rabbeted at its lower edge, as shown at-5, the lower sash being rabbeted at its upper edge, as seen at 6, upon the one face for cooperation with the rabbet 5 of the upper sash and at its lower edge it is rabbeted, as at 7 upon the opposite face of the sash for cooperation with a rabbet 80f the sill to form a water-tight joint. When the upper and lower sashes are in closed position, as seen in Figs. 2 and 8, the rabbets 5 and 6, interengaging as thev do, form Patented Oct. '7, 1919.

a water-tight joint, and, fitting tightly, serve I I as also clearly illustrated in Fig. 4, and each of these plates is wider than the thickness of the sash so as to leave a projecting por tion 10 beyond one face of the sash, as seen clearly in Figs. 3 and 4 and also in Fig. 6. These projecting portions 10 constitute tongues which on the closing of the sash enter grooves 11 in the stops 12 on the frame, making the window absolutely watertight and weather-proof.

The jambs 13 are grooved at the mill to form grooves 14 to receive metallic brace plates 15 secured therein by suitable means, as screws or the like 16, see Figs. 5 and 6, thus requiring no carpenter work upon fitting the plates' in position. These brace plates extend the full height of the two 4o respectively.

the plates 9 on I the sashes materially strengthening the latter. 7 e

The brace plates canbe installed on any old double-hung or single windows ,hyremoving the sash cords, weights and "blind stops, retaining the: old sashes. The sashes are mounted in the frame so as to swing outward and-to Jbereversedeaoh independently of the other, for clean ng or forfother purposes; As seen in Fig. :3', the

lower -sash has pivotally connected to its side plates (those on one side only. being illustrated, but itbeing evident that those "seen are duplicated upon the other side) as at 1 7 a'link or the like 18,..thispivotal connection being near the upper endof the sash, and at a point farther down substan- .ti'ally near-the mid-center there ispivo'tally connected therewith, at atl9, an. arm or the like 20, which latteris 'ofl'set, as at:2l, to

provide space-for the arm :18 in reversing;

the window, the opposite ends 50f. theqarms I I8 ancl20 being :pivotally connected, as at 22 and 23- respectively, with the brace plate 1 5, as seen in :F-ig. '2',theipoints or pivoting being illustrated -in:-Fig. :5.

To opposite edges of the upper sash 3 ('those 'on one edge only'being' shown) there are pivoted :arms and '25, the :former being pivoted to the plate i9ad'jacent the upperf-end of th'e sash, as seenat. 26, and the'otlier at apoint 27 substantially midway-the height of the sash :The arm is ofise't,:as at 28,:for the same purpose as the oj flsetin the arm r20, as :above described.

The opposite ends ofthese arms2t [and 25 are pivotally :connected aviththerbrace plates 15,' as seen in Fig. 2, theppo-ints offpivoting being il-lustrated in ,Fig. 5 at .29 .and 30 being necessary J-by- .reason of pathe inter-- engaging rabbets at the adjacent edges of the top and bottom sashes. Either sash can be turned into a horizontal position or com p'letely reversed, asindicated 1n dotted lines o in Fig. 2. As eachsash is closed, the

tongues 10 on the opposite edges thereof fit into the grooves 11 in the stops and form moisture and "weather-proof joints and the interenga-ging rahbets at the meeting edges of the sashes and at the bottom edge of the lower sash also constitute moisture and weatherfproof Ij0l1'ltS.' /Vll81l both sashes -are mo-ved tothelr outward pos1t1on, there as .an open ng clear from top to bottom.
